PMID: 16210532
Science. 2005 Oct 07;310(5745):83-6. doi: 10.1126/science.1117756.

The proton transfer mechanism between aqueous Brønsted acids and bases, forming an encounter pair, has been studied in real time with ultrafast infrared spectroscopy. The transient intermediacy of a hydrated proton, formed by ultrafast dissociation from an optically triggered...

Optics letters

Grunwald R, Griebner U, Tschirschwitz F, Nibbering ET, Elsaesser T, Kebbel V, Hartmann HJ, JĂĽptner W.
PMID: 18064247
Opt Lett. 2000 Jul 01;25(13):981-3. doi: 10.1364/ol.25.000981.

Multiple quasi-Bessel beams are generated by transmission of sub-30-fs pulses from a Ti:sapphire laser through refractive thin-film microaxicon arrays. Time-integrated intensity distributions at several axial positions and for pulse durations of 26 and 12.5 fs reveal significant changes of...

Ultrafast branching of reaction pathways in 2-(2'-hydroxyphenyl)benzothiazole in polar acetonitrile solution.

The journal of physical chemistry. A

Mohammed OF, Luber S, Batista VS, Nibbering ET.
PMID: 21604716
J Phys Chem A. 2011 Jul 07;115(26):7550-8. doi: 10.1021/jp202277t. Epub 2011 Jun 09.

In a combined study on the photophysics of 2-(2'-hydroxyphenyl)-benzothiazole (HBT) in polar acetonitrile utilizing ultrafast infrared spectroscopy and quantum chemical calculations, we show that a branching of reaction pathways occurs on femtosecond time scales. Apart from the excited-state intramolecular...

Gas phase bimolecular chemistry of isomeric C3H 6Br (+) cations.

Journal of the American Society for Mass Spectrometry

Heck AJ, Nibbering NM.
PMID: 24222056
J Am Soc Mass Spectrom. 1995 Jan;6(1):11-8. doi: 10.1016/1044-0305(94)00084-D.

The gas phase chemistry of C3H6Br(+) cations generated via low energy electron impact on various dibromopropanes has been studied by using Fourier transform ion cyclotron resonance mass spectrometry. Neutral substrate molecules that have been selected to probe the bimolecular...

Chemical ionization of phenyl n-propyl ether and methyl substituted analogs: Propene loss initiated by competing proton transfer to the oxygen atom and the aromatic ring.

Journal of the American Society for Mass Spectrometry

Bogdanov B, Matimba HE, Ingemann S, Nibbering NM.
PMID: 24203479
J Am Soc Mass Spectrom. 1996 Jul;7(7):639-52. doi: 10.1016/1044-0305(96)00002-5.

The mechanism of propene loss from protonated phenyl n-propyl ether and a series of mono-, di-, and trimethylphenyl n-propyl ethers has been examined by chemical ionization (CI) mass spectrometry in combination with tandem mass spectrometry experiments. The role of...

Excited-state intramolecular hydrogen transfer (ESIHT) of 1,8-dihydroxy-9,10-anthraquinone (DHAQ) characterized by ultrafast electronic and vibrational spectroscopy and computational modeling.

The journal of physical chemistry. A

Mohammed OF, Xiao D, Batista VS, Nibbering ET.
PMID: 24684387
J Phys Chem A. 2014 May 01;118(17):3090-9. doi: 10.1021/jp501612f. Epub 2014 Apr 17.

We combine ultrafast electronic and vibrational spectroscopy and computational modeling to investigate the photoinduced excited-state intramolecular hydrogen-transfer dynamics in 1,8-dihydroxy-9,10-anthraquinone (DHAQ) in tetrachloroethene, acetonitrile, dimethyl sulfoxide, and methanol. We analyze the electronic excited states of DHAQ with various possible...

Front Microbiol. 2021 Jan 29;12:625952. doi: 10.3389/fmicb.2021.625952. eCollection 2021.

Prosthetic joint infection (PJI) is a severe complication of arthroplasty. Due to biofilm and persister formation current treatment strategies often fail. Therefore, innovative anti-biofilm and anti-persister agents are urgently needed. Antimicrobial peptides with their broad antibacterial activities may be...

PMID: 33381142
Front Plant Sci. 2020 Dec 15;11:611607. doi: 10.3389/fpls.2020.611607. eCollection 2020.

Plant cell wall associated hydroxyproline-rich glycoproteins (HRGPs) are involved in several aspects of plant growth and development, including wood formation in trees. HRGPs such as arabinogalactan-proteins (AGPs), extensins (EXTs), and proline rich proteins (PRPs) are important for the development...

A computational study of the double hydrogen migration in the molecular ions of endo tricyclo[5.2.1.0(2,6)]decene.
